I work for an insurance company, that handles a lot of money for what's standard in my country (Uruguay). One of my coworkers found a flaw in the way the company set aside money to pay for the car repairs. He talked to the CFO, and the ensuing change ended up making the company quite a bit of money through interest (definitely much more than 75k pounds). The technical change itself took all of 15 minutes (a badly written SQL select). I'm still impressed at how insurance companies (and banks and other financial institutions) can still make money while being massively inefficient. At least in my country's case, I believe it's a combination of a huge cost of entry and stifling legal regulations, but banks at least are having their lunch eaten on the consumer lending front by smaller competitors (still no good alternative on other services like payroll and big corp. money management which is where the big margins are I guess).
